With the above primary and other incidental objects in view the invention consists of the construction, parts or their equivalents, and their mode of operation hereinafter described, and set forth in the claims.

Fig. 17 is a perspective view of the sliding bar, showing the hinged plate thereon; and Fig. 18 is a view showing the preferred order of arrangementof the special or department keys.

Like parts are indicated by similar charactors of reference throughout the several views.

Referring by letters and numbers to the drawin s, A represents the frame members, which are secured to the baselate A and which support the operating parts. B repre sents the indicators, C the registering-wheels, and D the typecarriers. E is a crank or operating member by which the several parts are actuated, the movements of the various parts being determined by the operation of the value-keys 1 the initial-keys 2, and the department-keys 3 or 3*, said keys being ar ranged in vertical rows in front of the ma chine. As shown, each set or bank of valuekeys contains nine keys, representing the nine digits, or they may represent multiples thereof in tens. T he first set or bank of keys represents the units of cents; the second, tens of cents; the third, units of dollars; the fourth, the clerks-initial keys, and the fifth the department-keys and special keys. The keys are mounted radially to the transverse shaft concentric guides 5 and are yield ceases inglv held out and are returned to their outvard )osition bv means of coiled s )rin s 6 which surround them and which are conlined between the guides 5 and the transverse pins 7, which pass through the stems of the keys and at right angles thereto.

Defiant plates-aidjace t to and at the rear of the keys are detent-plates 8 and 8", said plates being concentric to the shaft 4-, upon which they are supported by radial arms, the detent-plates cooperating with the value-keys and the detent-plates 8 cooperating with the initial and departmcni keys. 'lhese detent-plates and 8 prt vided with hooks having beveled faces 9 and recesses 10, said recesses being adapted to receive the transverse pins 7 on the keys, and thereby hold said keys in operated or depressed position, said plates being in turn supported by the pins 7 in a sligl itly-raised position against the tension of springs 11. The detent-plates S and 8 are also provided with a hook 12, a shoulder 13 01"13, and a shoulder 14 near the shaft #1, for purposes to be hereinafter specified.

Sliding plates.----i\ionnted at their rear ends upon the shaft i and at their forward ends upon the shaft 15 sliding plates 16 for the value banks of keys and 16 for the initial and department banks of keys'-there being one of these plates adjacent to each of the said detent-plates 3 am 8 Each of the plates 16 and 16 is provided with elongated slots, through which embrace the shafts 4.- and 15 extend, said slots permitting the said plates to be drawn endwise by springs 17, which are attached to the rear end of the plates and to the frame A. The rearward movement of the plates is arrested by the shaft t, which-engages with the forward end of the cooperating slot in. the plate 16 or 16.

The sliding plates 16 are normally held from rearward movement by the engagement of the shoulder 13 upon the detent-plate 8 near its lower end, with a notch 18 in the up per edge of the plate near the forward end of the latter. (See Figs. 4 and 17.) The plates 16 are locked in their forward position by means new to be described.

Mounted rigidly upon the transverse oscil lating shaft- 19, which is located at the lower forward portion of the machine, is a of lovers 20, said levers having cammed projections 21 extending rearwardly therefrom and normally resting upon pins 22, that are attached to the sliding plates 16 for the valuekeys. Said ca-mmed levers 20 are adapted to be lifted by said pins when either of the sliding plates 16 is drawn rearwardly by its spring 1.7, which movement will oscillate the shaft 19. Also rigidly mounted upon the shaft 19, opposite the initial-key bank, is a detent lover said lever being provided with a dettmt-hook 2 1', that engages with the pin on the sliding plate 16 )eneath the clerks-initial keys, as-is shown in Fig. 8. This detent-lever normally prevents rearward movement of said plate 16' until a value-key has been depressed; but when one of said keys is depressed and the sh af t 19 is escillated the hook-detent 24 is lifted out of engagement with the stud 22 on the said plate 16, and so far as this detent is concerned said plate is then free to move rearwardly.

The shoulders 13 of the special detentplates 8' of the initial and department key bank rest upon the inclined planes of the special sliding plates 16 and said detentplates are thereby held in such position that the pins 7 will not engage the faces 9 ol' the detent-plates when the keys are depressed, which construction permits the initial and department keys to he normally depressible, but not arrestable; but by the depression of a value-key the red 19 is oscillated in the manner hereinbefore described, which disengages the .hook-detent 24 from the stud 22 in the plate 16 of the initial bank of keys, allowing the spring 17 for the said initial bank to draw its sliding plate 16 rearwardly to a slight extent. Near their forward ends the sliding plates 16 are provided with L-shaped slots 25 into which extend pins or studs 27, that I project from the detent plates 8. Simulta neonsl-yw ith the first rearward. movement of the sliding plate 16 of the initial-key bank the detent 8 for that bank is allowed to drop slightly by sliding on the inclined plane 25 or the initial sliding plate 16*, which permits the stud 27, attached to the said detentplate, to settle down and engage ith a sh oulder 26 in the L-shaped slot 25 in. the sliding plate 16*, by which meansthe plate is held in an intermediate position. Nhen an initialkeyjs depressed w ith the detent-plate 8 in this position, the tran'sverse pin 7 in the key bears against the beveled face 9 of the dctentplate and lifts-the plate, thereby carrying the stud 27 from the shoulder 26 and permitting the spring 17 to pull the plate 16' rearwardly to the full extent of its movement in this direction.

It is obvious that if a machine is desired for cash transactions only it is not necessary to carry the sequence of the interlocking mechanism further than the initial-key bank, and I do not wish, therefore, to he limited to claims covering a construction. re-

quiring further interlocking mechanism to compel a correct sequential registration.

However, persons who do a credit business or who desire to segregate the same on the printed record require another row or bank of keys for securing the full ireneiits of this method of sequential operation. For this further purpose, therefore, there is mounted loosely on the transverse shaft 19 a sleeve 28, to which is attached a lever 20 carryinga cannned face 21, similar to the eammed faces 21 under the value banks of keys-said taehcd to the plate 16 and to thearm 39, so I cammed face 21* normally resting upon the stud 22, attached to the special sliding plate 16 beneath the initial-key bank 2. Mounted upon the said sleeve 28 is another arnr23, similar to the arm 23 under the initial-key bank, said arm 23 carrying at its upper end a h0ok-detent 24, which normally enga es with the stud 22 in the special sliding plate 16 at the rear of department-keys 3. As the sliding plate 16' for the initial-key bank is drawn rearwardly the pin 22 thereon, engaging with the cammed face 21*, rocks the sleeve 28 and lifts the hook-detent v24 from the pin 22 on the sliding plate 16 of the department-key bank, thereby permitting the said sliding plate to be drawn rearwardly byits spring 17 until it is arrested bythe engagement of the shoulder 26 in the L-shaped slot of said plate with the pin or stud 27 in the detent-platc 8 for the department-keys. As has been set forth with reference to the initial-key hank, this slight movement of the sliding late permits the said detent-plate to settle own, so that the department-keys will he arrested when depressed, and when depressed the pin or lug 27 will. he lifted out of engagement with the shoulder 26, so that the rearward movement of the sliding plate can he completed. T his further movement of the sliding plate for the department bank of keys results in unlocking the main 0 erating device or crank by means now to e de-- scribed.

Main operating dceice-The main operat ing device of the machine consists of the cranlelever E, (shown in Figs. 1, 2, 3, and 1 1,) that is mounted on a stud that projects from one of the frames A. Upon the hub of the crank is rigidly attached a gear 29, said gear meshing into a second gear 30, that is fast upon the main operating shaft 31, which extends across the machine and makes one complete revolution at each operation of the machine. N ear its left-hand end a doublearmed crank 32 is rigidly secured to the shaft 31 for operatingthe rock-shaft 4, hereinhefore referred to. Onthe outer face of the hub of the left arm 32 of the crank 32 is a hex-cam 33, Figs. 9 and 10, and on the periphery of the opposite hub 32 is a notch 34. Said notch 34 is adapted to receive a lockingdetent 35 on an arm 36 of a hell-crank 37, that is mounted on the shaft or rod 38, which rod extends across one sectionof the ma chine and is supported by the frames A. The arm 39 of the tell-crank 37 is provided .at its free end with a stud 40, that projects into a slot 41 near the rear end of the sliding plate 16 for the department-key bank. N ormally this sliding plate 16 is in its forward position, with the detent 35 in therecess 34. T he stud 40 will then he at the for ward end of the slot 11, in which position it is held by a spring 42, said spring being at engaged by their detent plates, so that their therecess 3 1, after which it rides fore th-eshaft 31 has completed a full revoluis drawuto:itsnormal forward position in the plate 16 1 the rear value-key ineifectual end the in when the; slit plate 16* for the def iiartnient key bank is released and drawn rearwardly hythe spring 1? the l:ellcrank 3'7 is oscillated. This lifts the detent 35 from on the pe riphery of the-disk 32" during the entire rotation of the shaft 31. However, the sliding plate-16 m returned to its normal forward positionhy means hereinafter descrihed hetionzandthe stud 40 passing to the rear end of the slot all-,whoro it remains until the detent. 35 is eed intothe recess 34 by the contraction or the spring 42, when. the stud slot 4']. 9 shows the parts just described after the sliding; plate has heen drawn forwardand-before the crank has completed its rotation.

.tloe thus described the construction is identical, so fares the side frames, rods, gears, andcontourdines of the keyboaros, targets, &c., are concerned, with that shown in the pateutshereinhefore referred to; but it cliffers therefrom in respect to the number. of operating parts employed. and in the increased utility of the machine. From said description it will be understood that the value lceysnre normally do ressiblo, but are also releasable after being engaged by their clstcntplates, while the initial and department keys are also depressihle, but are not depressionds ineffectual. The depression of a value-key operates through its sliding and the1lever 20 to lift the detentnook 24; for, the initial-keys, which releases the sliding plate 1,6 for the initial-keys and permits it to be drawn rearwardly by its spring 17 until it is arrested by the engagement of the stud 27 on the initial detentplate 8 with the shoulder 26 on said. sliding plate. The depression of an initiahkey then lifts the stud 27 until it is released from the shoulder, wl 'ch permits the initial sliding plate to be drawn rearwardly its full distance, thereby ring the, lever and the dotcnt-hook 2-1? to release the sliding plate 36 for the departmentdteys. This plate is also arrested in an intermediate position by the engagement of its shoulder 26 with the stud 27 on the diqiartment detent-pla as, after which, when adepartnlent-key is dopressed, the shrimp; plate is moved fully to by its spring 17, thereby lifting the detent-hook 355 and unlocking the operating member. it is therefore obvious that the machine shown can be operated only in the following sequence; first, the depression of a value-key; second, the depression of an initial key third, the depression ofa departi'nent-key- I The operation. of a clerks-initial departmentdmy prior key or a to the operation of a operating-lever is positively looked until the above sequence has been carried out.

[in oscillatin movement is transmitted to through an idler-gear 46 on a shaft 47, to the.

indicators B, that are mounted on a shaft 4-8, and to the counter-wheels C, that are mounted on. a shaft t shaft l at the rear of each bank of keys is a can'nplate 49, said cam-plate having an arm.

50, a pin 51, and a spring-catch 52. These cam-plates adapted to transmit the oscillating movement of the shaft 4 to the sectors -15 by the following-described means: Pivoted at 53 to the radial forward arm of each of the sectors is a bell-crank 53, said bells crank having at its heel a shoulder 54 andat its free end a pivotedv oscillating pawl 55. The outer end of this pawl is adapted to travel against the inner periphery of the detcnt 8 or 8, being held against the same by :1.

spring 56, that is attached to the short arm 57 of this pawl and to a pin 58 in the bell-crank lever 53. The friction between the hell-crank 53 and the sector carrying the same is-sullicient to prevent said arm from swinging loosely by gravity during the operation of the machine. When any sector 45 is at its extreme forward position, the free end of the bell-crank lever 53 on said sector contacts with the corresponding hook 12, that is formed on the lower end of the detentlates 8 and 8", which contact carries the heel of the lever 53 almost into contact with the face of its corresponding cam 49. Thereafter as the cam is oscillated rearwardly the catch 52 will engage the shoulder 54., and thus interlock the cam with the sector 45. This inter- Rigidly secured to the.

on is released from the notch 18 in the sliding plate 16, whereupon said plate is moved rear.- wardly and the detent rests upon the upper edge thereof. This of course holds the hooks 1" of the (latent-plates elevated; and' it is suchelevated hooks that engage the bell-crank 53 and rock theni inwardly in the manner above described. If there is no key depressed in a bank, the hook 12 of the corresponding detent will not he elevated, and the hell-crank ol' the segment correspoiuling with said detent will not be a'l'lertcd, so that there will he no engagement of said hell-crank with its cam 4.). (onsequently although the said cam is given its lull movement the segn'ient is left in its forward position.

it is obvious from the ftn'egoing description that the targets B will he turned to a position to correspond to the keys last operated and that the counter-wheels will he likewise turned, except under conditions hereinafter set forth.

.l will now describe the manner of returning the depressed keys and the sliding plates to and 16 to their normal positions.

The arms 50 on the earns 49 are each pro vided with set-screws 60 and 60: The screws 60 are adapted to engage with the rearward radial arm of the sector 45 and push it forwardly as the cam is swung in that direction. 'l he screws 60 are adapted to bear against the shoulders 14 on the hubs of the letont-plates 8, and as the cams complete their rearward inoveinet'lt said screws will raise the detent-plates slightly, thus releasing the pits 7 ol' the depressed keys from the recesses 10 in the said plate, so that the keys may he thrust outwardly by their springs 6. The time o l contact, however, between said screws 60 and shoulders 14 is such that when the handle lil has completed itsmovement the cams 49 are moved slightly forward, thus allowing the shoulder 14 on the hubs of the detei'it-plates to be relieved of the pressure the screws 60, so that the springs 11 may draw the detent plates dowinvardly into the notches 15 of the sliding plates 16 when they are carried forward. Extending laterally from each of the plates 16 and 16 is a hinged plate 61 and a stud 62, against which said plate is adapted to engage. The hinged plates 61 are each pivoted on a pintle 61, that passes through the plates 16 or 16. said [)llLtlO on its outer end carrying a short arm (53, to which and to a pin in the plate 16 .or lo are attached a spring 63 said spring being adapted to hold the free end of the hinged plate (51 normally against the stud 62. l lxtending laterally from each ol the cams 4:9 is a stud 51, which in its forward movement adapted to pass l'reely to the rear of the eorrespondiz1g hirged plate (31, providing the sliding plate to which the hinged plate is connerted is in its l'orward position. it, however, the sliding plates 1 (3 and w are released,

so that-they are in their rearward position,

the pirs 51 pass lretween the hinged plates (51 and the studs (32, said operation heing pernlittezl l the osrillation of said lunged plates about their pivots. hen the cams 45 have completed their l'orward n'ioveinent and the pins 51 have passed helow the hinged plates 61, said plates resume their normal positions by tile contraction of the springs 63. As the cams then return rearwardly the pins 51, pushing on 1 he rear faces of the hinged plates l3], cause the plates 16 and 16 to slide forwardly to their normal position, the pins 51 passing to a position above the hinge-plates oi, as: indicated in Fig. 4. When the plates to have thus been moved forwardly into their normal positions, the shoulders 13 of the detent-plates 8 are drawn by the springs 11 into the notches 18 in the slidin -plates. When the sliding plates 16 are moved forwardly to their normal positions, the detentplates 8 are raised by the beveled faces sliding under the shoulders 13, thus allowing the pins 7 of the depressed initial and de ertinent keys to he released from the re iiesses l0.

(Tr-n.- out for the re7is-tcr.When cash has been received, the amount is not only indicated on the targets or indicators 4. but it is also added to previous amounts received on the counter-wheels C. These counterwheels, which mounted on the shaft %8 are operated by means of gears 65, 66, and 67 on the said shalt 48 and by the interlocking gears 68, all of which gears are driven by the sectors of the value-keys, as described above and in the patents referred to. interlocking gears 68 are carried on rock-arm 69, WlliCl'l arms are rigidly mounted on the rock-shaft 69. These gears are normally out of engagement with the gears 66 and 67; but they are thrown into engagement therewith when the shaft 649 is rocked, which motion is secured by a link 70, which link has near its front end no tch 71, into which normally projects a pin on a rocker-arm '73, said rocker-arm being rigid on shaft 69*. The rear end of the link, whiehis forked to receive the shaft 31, has a laterally-extending pin T l, that is adapted to travel in the boxcam groove33 on the hub 32?, so theta rev-- olution oi the shaft 31 imparts a reciprocatcry movement to the link 0 and an oscillatory movement to the rocker-shaft 69*. The manner of operation thus far is similar to that shown in the patents referred to. When, however, is desired to operate special keys representing transactions in which no cash is 'receivedsuch as Change, Paid out, and Qharge-the forwardend of the link 7 O is so "that the pin 7 2 is out e1" engagement with-the'notch 71; which thus maintains the counter-Wheels C out of operation when such keys are operated. The following means are ernployed for aceolnplishing this result: Journaled upon the shaft 4, 9,) adjacent to the detent plate of the department-key bank, is an oscillating plate 75, said plate having inclined slots 76, that are adapted to be engaged by the cross-pins 7 in the special keys 3*, so that the plate 7 5 is raised and lowered The 4 by the cross-pins z are moved in and out. The plate has an upwardly-extending arm that carries a stud 77, said stud being situated directly under and i. contact with the l'orward end of the linlr 0 and being adapted upon the (pression of one of the special lreys to raise the forward end of the linl: 70 out of engagement with the pin 72 and to supp It said link in that position until the pin 7 released from the detent 8 i v hile held in this position the link 70 .may reciprocate in the manner described without oscillating the shaft 69, the interlocking gears 68 Being maintained out of engagement with the gears 66 and 67. The countenwheels are therefore cut out of operation. when any one of the special keys 3 is depressed.

Special keg, rclca sc tiounted upon the side of each of the detent-plates 8 is a bellcrank lever 78, the lower end of lever coincidini with the shoulder 13 on said plate. The arm 79 of the bell-crank lever is held against a pin St on the detent-plate by a spring 81, said pin preventing the lever from swinging forwardly. Outside the casing 82 a hand-lever $3, by means of which an oscillaiing movement may be given to the shaft 15, said hai'id-levcr being secured to said shalt. Mounted upon the shaft 15 at the side of the plates 16 are cams 84, said cams being adapted upon the oscillation of the shaft 15 by the leven'lfe to engage with the lower ends of the bell-crank levers 78 and to raise the detont-platcs suliicicntly to allow the cross-pins 7 of the depressed keys to be released from the recesses 10 of the detentplates 8. The sliding plates 16 are moved forwardly by the cams 8a bearing against the pins on said slides, this movement allowing the detent-plates 8 to be pulled into the notche 18 by the retractions of the coiled springs 11, said springs being attached to the lower ends of the detent-plates 8 and to the frame A. When the sliding plates 16 lnive been moved to their extreme forward position, the shaft 15 is returned backward to normal position, during which movement the cams 84, hearing against the bell-cranks '78, move them rearwardly, thereby tensioning the springs 81 so that when the cams pass the lower ends of the bell-cranks 78 the recoil of the springs 81 will return the belleranks 78 to their normal positions.

To prevent operating the crank E while the keys are being returned tonormal position by means of the hand-lever 5 .3, locking means is provided, shown in F 2 and 3, as follows: Attached to the shaft 15 inside the casing 82 is a crank-lever 86, which lever is connected by a link 88 to the short arm 01" a bell-crank 87, said bell-crank being pivotci on a bracket 89 on the heme A. the tree end of the long arm of the lever lies bctween pins 90, that project "from a bar 91.

the said special keys This bar 91 is supported in hearings in the frame A and the casing and when moved endwise by the oscillation of lever 37 it is engaged and disengaged from a recess or hole in the handle 93 of the crank E. Normally the bar is out of engagement with the crank-handle; but when the lever 83 is turned to unlock the depressed keys the bellcranlt will be rocked, which. will slide the bar 91 outwardly into locking engagement with the crank-handle. The crank it is pre vented from being turned bacluvardly in any part of" its operation by the pawl 94, that is pivoted on the frame A and engaged with the teeth of one of the gears 29 or 30.

Check and tape pnint'er'.lhe check and tape printer shown. herein is in many respects the same that shown and fully described in my preceding application, Serial No. 59,413, so that the l'ollowing brief description is deemed suliicient for this application: Mounted on the base-plate A oi the register, adjacent to one end oi the machine, is the base-plate270 of a check and tape printer Frame. 271 represents the inner vertical standard of said rrame, which standard is provided in its forward and rear portions with upwardly cik tending arms 272 and 273, respectively. The outer frame-standard, which is shown at 274, is extended upwardly opposite the inner frame-standard arm 272. The check-printer frame consists, primarily, of an inner frameplate 275 and an outer frame-plate 276, said l ramaplates being parallel and terminating at their rear portions in disk-like heads or enlargements 275 and 276. dournalcd in the head portions oi the frame-plates 275 and 276 is a transverse shaft 277. Between said frame-plate heads the shalt 277 carries a printing and feeding roll 278, said roll having formed on its periphery suitable type projections which may indicate suitable words, such as Amount purchased, Please pay cashier, o to. (See- Fig. 15.) At the ends of thc type-coveder portion of the periphery of the roll 278 are feedingllanges 29, and onthe outer side of the inner flange 279 I mount on said shaft 277 a gear-wheel 280. The sha t 277 is rovided with an extension on the outer side of the frame-plate 275,011 the extremity of which loosely mounted a pinion-wheel 281. Fixed on the extension of the shaft 277, bcyond the wheel 281, is a ratchct-whcel 282, (shown in dotted lines in Fig. 12,) witl'i which a spring-actuated pawl 233 is adapted to engage, one cndof which pawl is eccentrically connected with the inner face of the pmion 281. Mounted on a shalt 284-,4vhicli er:- tends between the heads of the check-printer side frames, in. the rear of and below'tho shaft 277, is a printing and feed roll 285, said roll carrying, as indicated more rl arly in Fig. 13 of the drawings, a printing-collar 286, the latter preferably having type.proiections Lil on its periphery. These type projections, which are indicated in Fig. 13, are adapted to print the name and address of a person or ilirin. (See Fig. 16.) At the sides of the printing-collar 286 the roll 285 is provided ith knurled flanges 287. (See big. 11.) The shaft 28% is driven by a gear-wheel 290, which wheel is secured. to said shaft and meshes with the wheel 280, that is secured to the shaft 277. Journalcd in front of and above the center of the roll 278 is an inkingroll 295, said inking-roll being formed of suitable absorbent material and having its periphery in frictional. contact with the faces of the type on the roll 278. 296 also represents an inking-roll, which roll is journaled above and in rear of the printing-roll 285 and the periphery of which is in contact with the faces of the type on said printing-roll. Journaled in the rear of the roll 278 is a platen-roll 297, which roll is adapted to press a strip of paper into contact with the type on. the roll 278. 298 represents a journaled platen-roll which performs a similar olliee for the printing-roll 285. 299 reprc sents a swinging yoke, which is located between the side frame-plates of the checkprinter at a point below and inv front of the roll 278. Through the parallel arms of the yoke 299 passes a transverse shaft 302, on which shaft are mounted printing-wheels 307, one of which appears in Fig. 13, said wheels having type-figures projecting from their peripheries, the type-figures on each wheel running from 0 to 9, Connecting the upper sides of the check-printer side plates is a bar The dating-wheel shaft 302 projects at its outer end into an upwardly and forwardly curved slotted opening 326in the side frame-plate 276, (seeFig. 12,) and the inner end of the shaft passes throu h similar slotted openings (not shown) in tie plates 271 and 275. In front of the mini bering and dating wheel above described I journal an inking-roll 328.

As indicated in Fig, 12 of the drawings, 1 secure to the rocksh.aft 4 a sector 329, by which the movement of the rock-shaft 4 is transmitted to the pinion 281, said pinion being driven by an idler 317, that is journaled on a stud 318, projecting from the side frame 271. I also secure to the inner side of the arm of the sector 329 a shorter sector 330, the teeth of which mesh with those on the periphery of a sector 331, which latter sector is carried on one end of a transverse shaft 332, which shaft is journaled in the check-- printer frame above the numbering and datin inechanism.

Mounted on the shaft 332 is a spring 84), the upper end of which engages the ferward side of a projecting-pin 340 on the sector 331, while the downwardly-extending free end portion of said s ring bears against tlte rearward side of the sliaft 302 and retains the that is adapted to drop latter in contact with the curved upper side of the forwardly-projecting foot portion of a plate 333 on said sector.

Below the numbering and dating mechanisin'hereinbefere described I provide a paperguide 341, this guide-plate being slightly bowed or curved, shown, and-having its forward portion provided with an upper side shearing-plate 3 1-2, between which and the body of the plate 341 is formed a paper-passage. As indicated, the shearing-plate 34-2 has rising from one side and adjacent to the inner end thereof a lug 3&3. The guide-plate 341 is provided centrally'on its up er side with a transverse platen-bar 344, w rich extends beneath the numbering and dating printingwheels. 345 represents a cuttingframe, the rear bifurcated end of which is pivoted to opposite sides of the guide-frame 341, while its forwardly extending portion terminates in arms 346, but one of said arms being shown-in Fig. 13. 34:6 indicates a spring-strip, one end of which is secured to tie rear and under side of t e guide-body 341 and the forward and free portion of which exerts a downward pressure upon the rear portion of the cutter-frame 345. As is shown in Fig. 13 of the drawings, I secure to the vertical forward end of the body of the cutting-frame 345 and "between the inner ends of the arms 346 an upwardly-projecting knife or cutting-blade 348, the upper edge of which is beveled or sharpened, as shown Secured to the outer face of this knife-blade is an upwardly-projecting guide strip or. plate 34-9, the'upper portion of the latter being inclined or curvedforwardly, as shown. 350 represents an inking device, which is inthe form of an oblong box, shown in Figs. 11

Mounted rigidly on said shaft 373 is a ca1n-sleeve 379, the letter being provided with a tangential projection 380. )n the inner side of the tapeprinter frame the shaft 373 carries cam-sleeve 388, which corresponds in form with the csmsleeve 379 and which, as prescribed for the latter, is provided with e. tangential arm or projection 380. (ilot shown.) Pivoted on pins 391, which project inwardly from the forward portion of the check-printer side 275 end 276, are the forward ends of parallel arms 392 of o. platen-yoke 393, the transverse rear bar of this yoke having mounted thereon a suitehle platen-pad 394. This platen-yoke frame is normally pressed downward by spring 395, as shown in Fig. 11. Connecting the yoke-arms 392 is a transverse bar 396, the latter having secured. thereon the front portion of s spring-"plate 397, the inwardly or reerwerdly extending portion of nhich projects beneath the tranvserse portion 393, .snic spring being also adapted to contact with the outer end of the cam projection 380 of the can'bsleeve 379. In the rear end portionof the printer franie and between the plates 37 and 372 may he journeled e guide-roller 398, (see 11,) and in front or this roller is supported an inking case and pad 39?). Through the reerwardly-extending arms 4% of this inking device extends e transverse shaft 481, which projects from the plate The hotly of this inking device is similar in construction to the inking device 350, being provided with en upwarrlly-projecting inking-pad 402. li'iounted on a shaft through the tape-printer side plates is a feed-roller, of rubber or siinilermateriel, 411. (See Fig. 11.) Above the mid portions of this roller are ournaled feed-idlers 4-12, the 'ieripheries of which are in frictional contact with the periphery of the roller 411.

Extending outward from the rear stzmdnrd 273 oi the inner Nameplate of the cheek-printer is a lined rod 413. On the outer end oi this rod or snalt H8 is loosely mounted a roll of peperelll. 432 represents a transverse shaft which has its inner end portion secured to and projecting outwa lly from a. forward extension of the check-printer side plate 276. Upon the shaft 432 in its inner portion ing formed with e. helf-tuhuler central projection 43.5.

The next disk is similarly formed, and the type represent the the clerks initials. The last disk to the left has a breeder face, and the type represent the department in which the transaction was made and as indicated on the deportinenh keys. are teeth 451*, adopted to mesh with pinions on shafts 453. Snid shefts 453 join nziled in the standards 27? and 2"3'and in the frames A end carry pinions 454, which mesh with the toothed hinge 255 on the tar i: that give :1 front indication, and also pinions s that mesh with the toothed flanges 455 7 of targets ll, that give it rear indicetion.

The constrimtion ol the printer is such. that when the shut" tion of the mechine the sector 329 will trans mit its motion to the pinions 381 and 374 on the shafts 277 and 373,respectively, through the idler 31?, whereby the v.-'1rious feeding and printing rolls are reused to operate, the feeding-rolls drawing the paper strips from the rolls 419, said strins heing conducted hetween' the various platens and typefaces,

On the remaining arcs of the disks diametrical ratio hetween the ninions- Ior,

is oscillated in the opcresea i whereby both strips are printed and the checksare cut off. '1 he oscillation of the shaft 4 also rocks the sector 331, which moves the plate 333thereon away from the shaft 302, thereby permitting the-spring 340 to rock the frame 299, carrying the numberingwheels 307 upwardly. As said frame approaches the upward limit of its movement a nose 324", that is formed on a plate that is journa ed on the shaft 302, engages with the bar 3 which turns said plate on said shaft. This plate carries transfer-pawls, and the movement thus imparted thereto carries the pawls back into position for effecting a transfer. As the plate is forced back to normal position by the sector the nose 324 engages the lug 343, which rock s said plate back to its norinal position on the shaft 302, thereby effecting the transfer.

Further details and specifications concerningthe printing mechanism may be found in my pending application, Serial No. 59,413,

' hereinb efore referred to.

. Operation: The operation of the-\machine is as follows: Normally the main operating lever E projects downwardly at the end of its travel and the sectors and indicators B will be in the positions determined by the registration made in the next previous opera tion. The slides 16 and 16 will he in their forward position, those (16) under the valuekeys being held therein by the detcntrplates 8 and those (16) under the initial and department keys being held in position by detent-hooks 24. The keys will be released and in their operative positions. if now, for instance, a registration is desired. to be made of by clerk E in the drug department, he presses the corresponding value-keys 1, and thereby raises the detent-platesS, releasing the sliding plates 16, which are drawn rearwardly by springs 17. As the sliding plates 16 pass'rearw ardly the pins 22 bear against the projections 21 on the levers 20, oscillate the shaft 19, to which said lovers are secured, and thus raise the detent lever 23 under the initial bank. This lever being also secured to the shaft 19, the detent is lifted out of engagement with the pin 22 on the sliding plate 16 of the initial-key bank, which. allows the said sliding plate to be drawn rearwardly by its spring 17 until it is arrested by the shoulder 26, which contacts with the stud 27 on the detent plate 8. Before being so released the sliding plate 16 held the detent-plate S at sucn a height on the inclined face 25 tlrat the pins 7 on the initial keys could not be engaged when dcprcsscd by the detents on the dctent-platc R; but as tlte sliding plate 16' is released from the detent-hook and is moved rearwardly into engagement v ith the stud 27 the detont-platc 8 drops sligl tly, so that as the initial key (E in this instance) is depre ed the pin 7 thereon contacts with the inclined face 9 of the def ant-plate 3 and lifts said plate sufficiently to raise the pin 27 above the shoulder 26, which allows the sliding plate to complete its rearward movement. By this movement the cam-lever 20 onone end of the sleeve 23 is raised, thereby oscillating the sleeve 28 and raising the detenthook 24? from engagement with the pin 22 in the slide-plate 16 under the departmentbank, after which a departmenbkcy (drugs in this instance) may be depressed and be arrested by its detent-plate. When the sliding plate 16 under the dcpartment-bank is released and is moved rearwardly, it carries with it the end of the lever 39 of the bellcrank 37, thus lifting the detent 35 on the lever 36 out of the notch 34 of the disk 3. on the shaft 31. The main operating-shaft is thereby unlocked, so that it may be turned by the crank E. During the first halfrevolution of the shaft 31 the crank-lever 44 on the roe; shaft 4 is raised, and the shaft 4, with the earn-plates 49, will be oscillated, whereby the screws 6O at the outer ends of the cam-plate arms will contact with. the rear arms of the sectors 45 and will. return said sectors to an extreme forward position, the pawls on said sectors contacting with the hooks 12 on the detent-plates just before the sectors 45 come to the end of their travei,

thus thro' 'ing the shoulders 54 toward. the cam-plates 49, so that they are engaged by the spr-ngcatches 52. As the sectors 45 move forward the indicators 3, with wlrch they are geared, and also the type-carrying disks D turned to zero, while the gears 65, 66, and 67 for the cormter-wheels O are not affected, as they are not at that time interlocked with the pinions In making this forward movement should the pawl 55 on the bell-crank 53 contact with a key that has been depressed, as is shown in. Fig. 7, the bell-crank will simply oscillate on its pivot 53 and pass said key without resistance. Also during the forward oscillation of the shaft 4 the pins 51 on the cam-plates 49 pass below the inclined hinged plates 61 on the sliding plates 16 and 16. During the return oscillating movement of the shaft 4 the spring-catches 52 on the face of the camplates 49 engage with the shoulders 54 of the bell-cranks 53, thus locking the cam-plates 49 to the sectors 45, upon which the be lcranks 53 are pivoted. This carries the said sectors 45 rearwardlynntil the end of the pawl 55 contacts with the inner end of a depressed kcy, when the bell-crank lever 53, to which it pivoted, is swung downward against the pin 59 and the shoulder 54 is released from the catch 52, whereby the camplate 49 is disengaged from the sector and is free to complete its rearward osci lation. The Oscillation of a tor totho point l by a depressed key causes 1% with which it is cared, to be where it is or the indicator turne'd suiiiciently to show the value of the key operated. it also oscillates the corre sponding type-carrier to a position for print ing the proper amount-and adds the same on the corresponding counter-wheel C, as will be more fully described. Just previous to the complete oscillation of the cam-plate 49, however, the set-screws 60 contact with the shoulders 14 of the detent-plates 8, lifting m said plates-slightly, so that the pins 7 are re leasedfrom the recesses 10, thus allowing the depressed keys to be thrust outwardly by v their springs c. When the shaft 31 has completed a'reyol-ution, however, the crank arm 32 hasb'cen carried a short distance past the center and has turn-ed the cam-plates 45 forward; thus relieving the detent-plates 8 of the pressure of the screws 60, which allows said plates to be drawn downwardly by the springs 11; However, said plates would still beheld upward by the sliding plates-16;. uponwhieh the shoulders 13 rest, 1f .it were not'for the fact that the said sliding plates are moved forward to their normal position 2 during-the rearward oscillation of the campia-tes 45, said movement being caused by 'thepi-ns 51', which bear against the rear sides of the hinged plates 6-1. Whenin their ex- ,treni' forward position, the shoulders 13 of 0 the-detent-plates 8 are engaged by theshou-l- 1 ders 1 8 onthe sliding plates 16, which prevent therearward movement of said plates Untilthe-detent-plates are again lifted by the depression of keys cooperating therewith.

5 The sliding plates 16* aremovedforward in a'm'anner similar to that just describe d ier theplates 16', an'dwhen so moved the in clirredfaces aredriveni under the shoulders of -thei detent-plates 8, thereby raising and l-r-old ing said detent-plates in a positionahove-the travel of the pins 7 onthe initial and department keys for the purpose previoiisiy described; The oscillation of the shaft 4 also operates the tape and check 5; printer as has been already described. As before referred to, the oscillation of a 'seetor' ii-nder a value-bank to the point Where iiidszhrested by a depressed key turns its corresponding counter-wheel C to add the 56 value of the depressed key to the amount already shown on the counting-wheels. This and the manner of throwing the idlers 68 into mesh with the gears 66 and 67 has been fully described herein and is also set forth in certain of the patents referred to. When the crank E and shaft 31 have each made a full rotation, the recess 34 is in position to receive the detent 35, which is then forced into said recess by the con-trac- .60 tion of the spring 42, so that the shaft 31 and the crank are locked against further manipulation until keys representing another transaction have been depressed.

The above description refers entireiy toj o 5 the operation of the register when cash is 'eeae'se received. I will now describe how the machine operates when "charge, or paid out, or change transactions are made, the'object being to indicate the character of the transaction on the indicators 47 and to print the same on the tape and check, but to maintain the counter-w icels out of oper ation. For this purpose pins 7 on the spe* cial-department keys 3 are made of sufficient length-for engaging the beveled faces of the cut-out plate which when the key is de= pressed is swung upwardly to lift the free end of the link 7 0, sothat as said link reciprocates the notch 71 will be out of engage ment with the pin ontherock-arm 73, there by allowing themachine-to be operated with out moving the idler-pinions-68 into engage mentwith the gears 66 and 67 for-thecorintor-wheels.

It will be observed that in the foregoing specification: and in the drawings the sequence of the operation provides for the following predetermined order of key do pression: first, the depression of' a value key; second, the depression" of aninitialkey, and, third, the depression of a depart mentkey.

I do not wish to be confined to this particular order, however, as it is obvious that where desired the depression of the department-keys may precede the depression of the clerks i-nitial keys, in which case the de-. partment-key' would-be o erated before the clerks-initial key can e effectively clepressed.
